通过研究早稻机插、抛秧与手插栽培的分蘖成穗规律，发现这3种栽培方式的分蘖利用均以第4、第5和第6叶位产生的分蘖为主；机插、抛秧和手插分蘖成穗率分别为80.0%、80.0%和95.8%，对产量贡献率分别为49.8%、46.6%和60.0%，说明机插栽培相比抛秧，其分蘖穗穗型较大，对产量贡献也大。
通過研究早稻機插、拋秧與手插栽培的分蘗成穗規律，髮現這3種栽培方式的分蘗利用均以第4、第5和第6葉位產生的分蘗為主；機插、拋秧和手插分蘗成穗率分彆為80.0%、80.0%和95.8%，對產量貢獻率分彆為49.8%、46.6%和60.0%，說明機插栽培相比拋秧，其分蘗穗穗型較大，對產量貢獻也大。

Based on the study of tillers and panicle formation in early rice with 3 cultivation methods, The author found that the tillers from 4,5 and 6 leaf position were main tillers. The panicle percentage from tillers in machine-transplanted, seedling throwing and hand-transplanted rice were 80.0%,80.0% and 95.8%,and the contributive rate to yield were 49.8%,46.6% and 60%, respectively. The panicle type of machine-transplanted rice was bigger, and had bigger contribution to yield.
